just wondering if anybody used them on any custom turbo setups ?? i building my car right now and was wondering the potenial of them

 

If you're running a pair of em with twins, they'd work pretty well, as a single I wouldn't want to try it. They're a restriction even on a 4.3L though much less a 350.The inlet was about 2 inches ID on mine, even though the outlet was huge. If you have one you may consider a modified inlet neck, but I'd sell it and look for either a large air to air. The cool thing about it is that if you wanted to you could have a tank you could fill with ice when you were going to a race.
